Abstract

The invention relates to a method for efficiently and accurately detecting the content of melatonin in peonies. The method comprises the steps of preparing a reference substance solution, preparing a test sample solution and detecting by high performance liquid chromatography-tandem mass spectrometry. The chromatographic peak obtained by detecting the melatonin in peony in the present invention can achieve baseline separation from the chromatographic peaks of other components, and is a symmetrical Gaussian peak with good peak shape, which can meet the qualitative and quantitative requirements; the melatonin in peony provided by the present invention The content detection method has the advantages of simple operation, high sensitivity, strong specificity, good stability, and accurate and reliable results.

Description

technical field [0001] The invention relates to a method for efficiently and accurately detecting the content of melatonin in peonies. Background technique [0002] Peony (Paeonia lactiflora Pall.) is a perennial herbaceous plant of Paeoniaceae, which has high ornamental and medicinal value. The medicinal use of peony is mainly to extract its root system, and its aerial parts have no other use except for ornamental purposes, especially the petals. After the flowering period every year, the petals fall all over the ground, which has virtually caused a huge amount of resources. waste. Melatonin is an indole neuroendocrine hormone that has attracted much attention in recent years. It has many important physiological functions for the human body, such as improving sleep quality, enhancing immunity, slowing down aging, anti-tumor, Antioxidant and regulate circadian rhythm etc. Previous studies have shown that after eating fruits and vegetables rich in melatonin, the level of m...
